Hi guys,

I am currently building a gaming computer. Altough I already chose most of the parts, I still want to know what PSU should I go with...
All the hardware:

CPU: Intel i5 4670 3.4 (no overclock planned)
CPU Cooler: Cooler Master Hyper 212 Evo
Mobo: MSI Z87-G41
GPU: MSI Geforce GTX760 2GB Gaming
RAM: G.Skill Sniper Series 8GB (2x4) 1866Mhz CL 9
HDD: Western Digital Caviar Blue 500Gb 7200rpm 16MB
SSD: OCZ Agility 3 120GB Sata III
Case: Zalman Z5 Plus
Monitor: Asus VS247H-P 24" 60hz Monitor
Fan Controler: Bitfenix Recon
Fans: 3 to 4 silent fans
Keyboard: Roccat Isku
Mouse: Logitech G9X

If possible something from 100$ to 130$. Also, i would like at least a bronze certified. And if you could get a modular one...

Thanks,

Unless you have an unusual situation (i.e multiple water cooling pumps, multiple CPUs, a dozen HDs , etc), your GFX card will determine PSU size and you can find this information on card manufacturer's web site:

Thermal and Power Specs:
97 - C Maximum GPU Temperature (in C)
170 W - Graphics Card Power (W)
500 W - Minimum Recommended System Power (W)
Two 6-pin - Supplementary Power Connectors


So 500W for system and 1st card + 170 for 2nd cared in SLI. This case / PSU combo would be perfect. Corsair 500R w/ TX750 V2 if you want to allow for potential future upgrade to SLI at $170. Your case ($50) + $130 PSU budget = $180 so within budget. NOTE: To do SLI ya would need to upgrade to the MSI Z87 G45 as the 41 isn't multi card capable.

With a 650 watter (good for single card) ... the combo is $170

Corsair HX is top of the line (tho 1000 and 1050 watters are dogs). Corsair TX V2 series is very good..... Any Corsair with an M suffix oir CX series, I'd avoid.

Seasonic X series is top of the line..... XFX Core Edition and Antec HCG / HCP series is equivalent to Corsair TX V2

This is at the top of your budget, and much more power than you will need with that build, but it is semi-modular and Haswell certified, and with free shipping:
CORSAIR HX Series HX750 750W ATX12V 2.3 / EPS12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
129.99, with free shipping.
Another good unit, not quite as good as the HX above, but semi modular and less money:
CORSAIR CX600M 600W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Modular Active PFC Power Supply
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Both of these have the main power (24pin) and EATX Aux. power (4+4pin) wire hardwired to the PSU, the rest are modular. The HX has enough power to allow adding another GTX760 later.

Pick any Corsair, Seasonic, XFX, PCP&C, Antec, or Enermax in the 550-650 watt range. Pick the one that has all the features that you want/need, that has the lowest cost.

You should be good to go.

Keep in mind that this is the abolute minimum and won't support a lot of hdd's and usb-loading devices simultaneous. Also, a psu is much more efficient when not working on it's highest capacity. So consider a 550-600W as good. And choose a reliable brand like Seasonic, XFX, Corsair or be quiet!

A good 500 watt PSU will work in your build. If you plan to SLI I would suggest you move to a 750 watt PSU.

Newegg has a really good deal going today on a Corsair HX750 if you want a PSU to possibly SLI later. Its only slightly more than a high quality 500 watt PSU due to the $40 off today.

1. Brands are not a guarantee of quality..... even lines with a brand have to be checked..... Corsair HX series consistently gets 10.0 jonnyguru performance ratings but the 1000 ad 1050 get an 8.5 and a 9.0. The CX is Corsair's budget line (like Antec Basiq) and doesn't belong in a high end system .... the TX series with M suffixes also don't score very well. I have copy / pasted an old THG from 01/01/12 post below ....some of the manufacturers may have switched since then.

2. 10 watts per HD ... which is why I listed lotta those as an example of non applicability. Each USB device adds 2 watts. You can check this by loading them up 1 by 1 here:

http://extreme.outervision.com/PSUEngine

3. PSU's hit peak efficiency at 50% load, but we don't double out sizes to accommodate this at peak load.

Also, advice about brands should be taken with a few pounds of salt :) . Which of the following do you think is true ?

Antec makes crappy PSU's
Antec makes good PSU's
Antec makes very good PSU's
Antec makes great PSU's

The answer .... all of the above. Manufacturer's are in business to make money ... the more they sell the more they make. Targeting a single market segment limits the number of customers you can sell to, limiting the amount of sales. So most vendors sell to multiple market segments:

Great PSU's

Most Corsair PSU's are in fact made by Channelwell...who makes:

The entire CX series except for the 400
The entire GS series
HX750, 850 and 1000
Entire TX Series except for 650

Seasonic makes their :

AX750 and 850
HX650 and smaller
VX450 and TX650

Their flagship AX1200 is made by Flextronics

I didn't mean to imply he should buy blindly from a brand I recommend. But no one would claim all brands are equal. There are just those who only make crap (which are often aliasses for the big manufacturers that also make good psu's under another name, I know). When I write an answer in order to help someone out and recommend them some brands that often deliver good products, I don't mean to start a brand-war by omitting some other good brands for the sake of simplicity.

To adress your other two points: I do use such a calculator from time to time to check if my recommendation is correct, but the many similar available versions differ greatly in the resulting wattage. Of course you should not double a psu's capacity to reach optimal efficienty, but it does decline exponentialy towards full load, so keeping a little margin just prolongs the life and minimizes the bill.

Thanks for the advice,

I am from Portugal and I can not get that combo so I'll stick with the Zalman Z5 Plus. I have made my research again, based on what you told me and... maybe I'll go with the TX750 v2! However do you think the GS800 from Corsair is also good? It fits my price range and I've read some good reviews on it. Maybe you will say that I don't need that much power, but I might upgrade in the future to an SLI configuration and I will get some other HD and stuff like that so...

Your welcome. Either of those should serve you well. My preference would be the TX.
